Sadly, it's much easier to create a desert than a forest.

The big threat to the planet is people: there are too many, doing too well economically and burning too much oil.

Composing computer programs to solve scientific problems is like writing poetry. You must choose every word with care and link it with the other words in perfect syntax. There is no place for verbosity or carelessness. To become fluent in a computer lnaguage demands almost the antithesis of modern loose thinking. It requires many interactive sessions, the hands-on use of the device.
